前两天和一位同行聊起来：给传统的tp型数据库，增加列式数据处理能力，比如存取parquet数据、比如增加时序型数据的处理，好像还有点搞头。
有不少给postgresql增加了这些能力的项目了（例如pg_duckdb），我在想：也许也可以把这些做法照搬到sqlite上面。
另外，他也提到另一个观点：对于大部分企业来说，时序类+文本搜索类场景，应该覆盖了90%以上的AP需求了。

Secret Chats are one of the service’s additional security features; it allows messages to be sent with client-to-client encryption. This setup means that, unlike regular messages, these secret messages can only be accessed from the device’s that initiated and accepted the chat. Additionally, Telegram notes that secret chats leave no trace on the company’s services and offer a self-destruct timer.
The cloud-based messaging platform is also adding Anonymous Group Admins feature. As per Telegram, this feature is being introduced for safer protests. As per the Telegram blog post, users can “Toggle Remain Anonymous in Admin rights to enable Batman mode. The anonymized admin will be hidden in the list of group members, and their messages in the chat will be signed with the group name, similar to channel posts.”
